This inventionrelates to improvements in paper-making apparatus and is directed more particularly to improvements in cylinder papermalring machines.

The 'principal objects of the invention are directed to the provision of paper-making apparatus wherein a cylinder mould is adjustable relamen:s.

In paper-making apparatus of the type to which the invention relates, a cylinder mould rotates in a vat which is provided with a wall or walls adjacent the mould, there being a space between the mould and wall for paper-making material and the fibers of said material being taken on by the foraminous" surfaces ofithe mould.

In order to produce certain results insofar as possible the wall or walls have been of certain contours and spaced certain distances from the cylinder mould. That is to say, when it is desired to produce a certain kind of paper it has been customary-to locate the wall or walls adjacent the cylinder mould and so form the vat as tive to the adjacent wall or walls of the vat in order to meet various conditions and requireconstant it is impossible at times to use thematerial desired so that it becomes necessary, in order to produce the said other result, to vary the type of paper-making material and/or speed of the cylinder.

According to this invention, instead of varying the numerous factors in order to produce a certain result or a certain kind of paper or instead of attempting to make the various factors accommodate themselves to the definite relationship .of the cylinder mould and adjacent wall, there is provided a wall or walls adjacent the cylinder which are of such shape as to suflice for general purposes and the cylinder is adjustable relative to the wall or walls. More specifically Tthe cylinder mould is movable back and forth and to provide a certain space between the mould and wall and to use paper-making material of certain consistency and rotate themould in a certain way.

In other words, for certain predetermined resultsthewall isofacertainshapeandacertain distance from the cylinder mould, the characteristics of the paper-making material for the particular result are more or less definite, and the speed of the cylinder is within a certain range. The space between the cylinder and-wall is, of

'course, constant and therefore an important fac ties, the cylinder and wall must have a certain relationship; to produce another result with the same or diifereut paper-making material the cylinder and wall must have a dilferent. relationp. But this relationship is .essentially up and down relative to the vat and the wall or walls adjacent thereto so as to provide a varying space between the cylinder mould and wall.

It is possible by means of this invention to set the-cylinder mould to provide either a relatively small or great space between it and the adjacent with a certain result to be obtained by" the use of a certain paper-making material, a certain operating speed, etc., the mould may be located with reference to the adjacent wall or walls to provide such a space as will operate to the best advantage with the other factors to give the" desired result. For instance, to produce a certain kind of paper with a paper-making material having certain characteristics-the space between the cylinder and wall may need to have a certain form while to produce another kind of paper with the same or another type of paper-making material the space may need to be difierent.

The adjustability of the cylinder relative to the adjacent wall or walls therefore makes it possible to producethe desired results by the use of paper-making material best suited for those're- I sults. The paper-making apparatus is variable to accommodate the desired results and. condi- The invention may be practiced in various ways but for purposes of disclosure the following description refers to the accompanying drawing wherein:

Fig. 1 is a side elevational view of paper-making apparatus embodying the novel features of the invention; and

Fig. 2 is an enlarged partial plan view of one side of the apparatus shown in Fig. 1, to explain the novel features of the invention.

Referring now to thetdrawing more in detail, the invention will be fully described. 4

So much of a paper-making apparatus is shown and described as is necessary for the purposes of disclosure and it will therefore be appreciated that the other necessary parts may be used in association therewith.

The paper-making apparatus of the invention generally includes a vat 2 in which is rotatable a cylinder mould M.

The vat has front and rear walls such as 4 which may be of metal or the like and there is a bottom wall 8. A transverse wall 8 extends between the members 4 as does a vertical wall l0.

These walls 8 and III are arranged to provide a chamber into which paper-making material is admitted and which may pass up and over the vertical wall 18. A-curved wall W which is more or less semi-circular as shown is provided between the walls 4 and it is relative to this wall W that the cylinder mould is movable.

A bottom wall l2 extends between walls 8 and i and a horizontal wall l3 extends between wall l8 and wall W. A, horizontal wall l5 extends between wall W and a wall IS. A plate l4 adjacent the inner side of each of the walls 4 is slidable thereon in all directions at right angles relative to-the axis of the cylinder mould.

Each plate l4 has a'horizontally disposed ledge or shelf l8 and an upwardly extending partl8. A bearing on each of the shelf, parts l6 of the plates l4 and indicated by 20 rotatably receives a shaft M? of the cylinder mould whereby the mould is rotatably supported by said plates 14.

Annular flanges '22 and 24 of the mould and of the plate respectively are provided on which a sealing ring or strap may be disposed. Hubs IQ of the plates l4 have pivoted thereto at 26 the upper ends of rods 28 and 30 as shown.

A pair of shafts 32 and 34 are rotatable in the vat walls 4 and on these the rods 28 and 38 are oscillatable, adjacent the plates 4 in brackets 38 and 38 respectively. The .brackets slidably receive the lower ends of the rods 28 and 38.

Thelower ends of the rods 28 and 30 are threaded and threadedly engage nuts such as.

44 disposed between bearings 48 of the brackets.

The nuts 44 are in the form of worm gears which are in operative engagement with the shafts 32 and 34 by means of worms '48 and wheels such as 58 are secured to the shafts 32 and 34 to facilitate rotation thereof.

As the shafts are rotated the worm gears are rotated thereby so as to move the rods 28 and 30 axially in one direction or the other accordends of said shafts 36 and 38 so that as said shafts are rotated the rods at opposite sides of the vat are actuated.

By means of the construction described it is possible to move the plates l4 up and down or back and forth at right angles relative to the horizontal axis of the cylinder mould and thereby move the cylinder mould to various positions of adjustment relative to the wall W for the purposes before mentioned.

While I have described the invention in great detail and with respect 'to the present preferred form thereof, it is not desired to be limited thereto since many changes and modifications may be made therein without departing from the spirit and scope of the invention.

a What it is desired to claim and secure by Letters Patent of the United States is:
